dar_cp: 'cp' clone command that is able to copy data located after an I/O error

NAME

dar_cp - 'cp' clone command that is able to copy data located after an I/O error

SYNOPSIS

dar_cp <source file> <destination file>

dar_cp -h

dar_cp -V

DESCRIPTION

dar_cp is similar to the standard 'cp' command, except it does not stop copying when an I/O error is met. Instead, it skips a bit further and continues to copy the rest of the file, as much as possible, filling the gaps by zeroed bytes.

dar_cp only accepts full filename (not directory) as argument. The reason of its existence in dar package is that you need it if you use Parchive with dar and have a corruption on a CD-R or any other read-only medium. You need to copy the corrupted slice on a read-write filesystem, for Parchive be able to repair it using slice associated redundancy files.

OPTIONS

-h

-V

SIGNALS
